This invention relates to wrecking poles or bars for wrecking and dismantling wooden buildings, frames, roofs and for tearing down or dismembering wooden and fibrous structures. 7

It is an object of my invention to provide a simple and highly efficient implement which will expedite and facilitate the wrecking FREDERICK w. Jonnsonfor EXCELSIOR, MINNESOTA, ASSIGNOR To HEivRYBEIN RT,

Fig. 4 is'a View oftheoperating end of the implement. g I

My implement includes an "elongated straight handle or pole havingashankreceiving socket 5a atthe outer end thereof.

and dismantling of the wooden .and fibrous 1O structures, such as the walls, ceilings and roofs of buildings.

My implement, while adapted for wide general use for wrecking purposes, is especially Well adapted for use by firemen in penetrating walls and ceilings, dismembering roofs and shingles in gaining entrance through Walls to fire or smoke.

More specifically it is an object of my invention to provide a wrecking implement 1n the form of an elongated. pole having a thrust head provided with a chisel edge extremity for penetrating and splitting material and havin a wedge portion and a hook portion which is adapted to be guided conveniently through material by the chisel edge and wedge portion and which will engage ma terial after penetration has been effected.

These and other objects and advantages of the invention will be fully set forth in the following description made in connection with the accompanying drawing, in which like reference characters refer to similar parts throughout the several views, and in which 2- Fig. 1 is a side elevation of an embodiment Fi 3 is a side elevation of the implement turned 90 degrees from the position shown in Fig. 2, and

A head preferably constructed ioffsteel or other hard material, which will maintain an edge is secured to said socket and projects longitudinally of the handle 5, said head in cluding a tapered shank 6 preferably of square cross section which is'tightly fitted in socket 5a of the'handle. Theouter extremity ofthe head is of chisel shape terminating in a sharp edge 7. Thein'termediate 'por' tion ofthe head on one of its surfacesdspro;

vided witha reenforcing and wedgegrib 8 which tapers from'its center to its'ends, as clearly shown in 3. The headalsoii1-- cludes a laterally projecting hook',9 which is of approximately the thickness of the chisel head and hastan inclined edge 9a and termirection of the handle. 3

A metal thimblelfil may surround the outer end of handlei5' protecting the socket and shank, and if desired, apin or rivet 11 nates in a point 96 which 'projectsin the dimaybe inserted diametrically through 'the handle, thimblefand. inner end of thesliank to more positively secure tliesaid parts tor- In operation the implement may'fbe'thrust longitudinally through a wall or ceiling, the chisel edge 7 easily splitting and penetrating the material and effecting an 'opejningjsufiicient to readilyaccommodate thelater'ally projecting hook 9. The wedg'e'action of the rib 8 assists in splitting or'increasin'g the sizeof the opening and a powerful thrust may be obtained since the head extends longitudinally of the handle ratherthari laterally;

thereof. 1 p

In many instances after penetration is efjfected it is desirable to tear away or remove boards, shingles or other material and this may bereadily done by turning the handle V shingles from the roof and material may be torn away by engaging the hook of the same and pulling the implement rearwardly.

When-used by firemen the hook is also of advantage, enabling the fireman to grasp the peak of a roof or an over-hanging mem- ;ber to steady his foothold.

The device is equally applicable for strip ping wainscoating, flooring, mouldings or mop-boards. I

From the foregolng description it will be i seen that I have provided asimple and high- 1y eflioient wrecking implement adapted to penetrate and dismember wooden and'other fibrous s uc ures- It i l, of co r e, be understood,that various changes m y be made in the form, de-
